Porcelain enamel station sign. Rector Street (R/W), 1970s. This is the only remaining sign in Standard Medium among a group of stations on the BMT Broadway and Fourth Avenue lines that were renovated with large colored tiles in the 1970s. Regarding the disappearing mosaics, a TA spokesman said at the time, “We didn’t consider these things had any great artistic merit anyhow.” (2008)
